Cambridge Quantum Computing

Cambridge Quantum Computing (CQC) is a quantum computing company that develops architecture-agnostic, enterprise quantum solutions to address industry challenges. Founded in 2014 and based in Cambridge, UK, CQC focuses on quantum computing, quantum machine learning, and quantum cryptography. The company provides software and consultancy services, aiming to create world-changing businesses through quantum technology. In December 2021, CQC merged with Honeywell's Quantum Solutions division to form a new entity called Quantinuum. This merger created what was claimed to be the largest and most advanced integrated quantum computing company in the world at the time. Quantinuum aims to bring quantum computing products and solutions to large, high-growth markets in the near, medium, and long term as quantum computers scale in capacity and quality. The company planned to launch a quantum cybersecurity product in December 2021 and a broader enterprise software package in 2022. Quantinuum also announced plans for major upgrades to its System Model H1 quantum computer, although it remains platform-agnostic, providing clients with other firms' quantum systems where appropriate.

Key customers and partnerships

Quantinuum, the entity formed from the merger of Cambridge Quantum Computing and Honeywell's Quantum Solutions division, has partnerships with major cloud computing providers. CQC's quantum computing systems were made available via all major public cloud services, including Microsoft Azure, Amazon Web Services (AWS), and Google Cloud. This allowed researchers and businesses to access quantum computing power through cloud platforms. Additionally, the Japanese telecommunications company and tech investor SoftBank Group invested in the company and partnered to bring quantum computing capabilities to other tech companies in its portfolio. In May 2023, Quantinuum's most powerful computer, Aria, became available through an Amazon AWS service, further expanding its reach to potential users in various industries.
